XFX Radeon HD4670, no signal on monitor when used.

Don't wanna be that person, but *she, lol.

So I've updated (to the best of my ability) my system specs, so you guys can click on them to assess what would be the best PSU to remedy this problem. If there is anything else I can do to further this, let me know.

You should edit the ram memory info- is it a single stick of 4 Gb or are there 2 sticks of 2 Gb. If you know @ wich frequency they are, it would be good to write that too. Use the PSU calculators to see how much are you using now and add ~200 W to be safe with the new graphics card.

Scrolling down, under Memory, is my ram. Friend gave that to me also.
I think I put in everything mostly correct in the calculator and got like 275, but I don't think that sounds right. Plus 200 would only be 475 w. I was just gonna go with a good 650 w or greater PSU, if anyone could point me in the direction of a good one.

Ok. I deffinetly miscalculated !
I would certenly go for the 650+ psu and maybe a Corsair,Seasonic, Antec...

I was looking at this one on Newegg, what do you guys think? It kind of stinks though because I can't return the PSU and I have nothing to do with it. :/

When did you buy the Coolmax 400w ?

When did you buy the Coolmax 400w ?

Bought it from Newegg last month on the 14th. Unfortunately I'm just barely over the 30 day period.

With 62 amps on the 12 V rail, wich is single, 80+ efficiency and 750W.. no comment needed. Maybe a less powerful psu would do the job for you, but when making a pc, never save mony on the power suply! If its weak and bad ,the entire system can "die".

Smart choose, go for it!

 

[DocBrown]

If you still have the box it came in, Call customer service tomorrow. Explain it is not enough watts for your card. Tell them you want to buy the one you linked to above. I will bet they will let you send it back for credit since you will buy the new one. I have bought $$$$$$ from NewEgg. They are always willing to work with the customer.

Thanks, I plan to upgrade little bits and pieces of the computer as time passes, so I went with a more powerful psu just to play it safe. I'll wait to make the purchase in case anyone else has anything to say about this.

Oh great, hopefully they'll be cooperative. Thanks for the idea.


Edit: I can't call until Monday, service hours are only Mon-Fri. I'll let you guys know how it goes.

So are we certain that the problem is the psu? Just to clarify, every fan spins when I turn the computer on with the graphics card inserted to the mobo. The power button will turn the computer on but cannot turn it off.

I'm also debating whether to buy the new psu tonight (with one day shipping it would be here faster, and I am really anxious to get this all working) and ask them about sending the original back tomorrow, or just buying tomorrow.

What do you guys think?

EDIT: I just read the max TDP on my cpu is 65 w. Not sure if this affects what we believe to be the issue.

 

[InfernoRogue]

Alright guys, sorry for so many posts, but it's decision time. If we all agree that this really is the fault of the psu, I'll call newegg right now to return the other one. Thoughts?

 

[petko131]

I agree that it's the psu. Wait for some more answers...

 

[InfernoRogue]

I'm gonna go ahead and order that 750 w psu I linked to earlier. If it doesn't fix the problem, I can just return it.

Unless anyone else has anything to say?

 

[InfernoRogue]

So the new psu didn't work. But my friend told me that he tried the vga slot on the card like I am and it didn't work for him either, then he had to use a vga to dvi converter so it worked in the other slot. And then it began to work. Also he said that vga worked only when he used dual monitors, so I don't know what's going on. I'm really scared about not knowing what the problem is, I'm going to try the adapter thing tomorrow.

Well why didn't your "friend" tell you that in the first place

 

[InfernoRogue]

I have no idea. But the adapter didn't work either. I used a vga female to dvi-i male adapter, didn't work. I'm really scared guys, I have no idea what the problem is.

Not sure if I mentioned this already, but the usb ports don't work either when I have the graphics card in the mobo. It seems like none of the cables connected to the motherboard from the computer case function when the graphics card is in, like the led lights and such.

 

[petko131]

After replacing the PSU with a 750W one, after trying out some adapters, the combination still doesn't work.
That leaves only one thing: The GPU doesn't work!
We all (including you) believed that the MoBo and gpu worked in your friends pc but with a more powerful PSU.
You replaced the PSU, and the problem isn't solved.

At this point, I would take out the card your friend gave you, and go back to him/her and test it in his/hers PC to see if it even works

 

[InfernoRogue]

Would a bad GPU have anything to do with the usbs, lights, etc not working upon start up? It seems like the computer turns on, a few leds are on for a second, then they all stop. Almost as if the system is stuck in the moment before the bios or anything really loads.

I'm really hoping it's just not the specific pci-e x16 slot on the motherboard, replacing that would be a big pain.

Does everything work if you remove the card and use the on-board graphics? I know you said this earlier, but is it still the case?

One thing that is often overlooked is motherboard alignment in the chassis. Remove the graphics card, slacken all the mounting screws (don't remove them, just undo them enough so that the board is free to move slightly) and then replace the card. See if that makes any difference.

 

[petko131]

While doing what Dwarf said, you must be grounded. While unscrewing the motherboard, your forearm (Roll up your sleeves if you have them) must be touching the edge of the case in order to discharge the static electricity that piles up on our skin and clothes. You must be careful not to damage any "little barrels" (capacitors) with the screwdriver you will be using.
Of course, you must unplug ALL cables, and before pulling out the power supply cable, turn of the little switch to O. Put the PC on a flat area and begin.

I tried what you guys said, no change.
